Expose the experimental permission and question HttpApi server as Effect layers and test it through NodeHttpServer.layerTest and HttpClient instead of an imperative listen API.
Move the permission slice onto the parallel Effect-native experimental HttpApi server, stop extending the Hono mount path for this PR, and keep the question and permission groups served through the direct Effect server boundary.
Move the shared permission route DTOs to Effect Schema, mount a parallel permission HttpApi surface, and cover the new list/reply/docs flow with a server test.
